RCrossing vehicles: Active Distance AssistDISTRONIC may mistakenly detect vehiclesthat are crossing your lane. Activating ActiveDistance Assist DISTRONIC at, for example, atraffic light with crossing traffic could causeyour vehicle to pull away at the wrong time.
In such situations, brake if necessary. ActiveDistance Assist DISTRONIC will then be deacti-vated.
Active Distance Assist DISTRONIC with
Active Steering Assist
General notes
Active Distance Assist DISTRONIC with ActiveSteering Assist aids you in keeping the vehicle inthe center of the driving lane by means of mod-erate steering interventions in a speed rangefrom 0 - 125 mph (0 - 200 km/h).
It monitors the area in front of your vehicle bymeans of multifunction cameraC, which ismounted at the top of the windshield.
In a speed range from 0 - 37 mph (0 - 60 km/h),Active Steering Assist focuses on the vehicle infront, taking into account lane markings, e.g.when following vehicles in a traffic jam.
At speeds of more than 37 mph (60 km/h),Active Steering Assist focuses on clear lanemarkings (left and right), focusing on the vehiclein front only if clear lane markings are not pres-ent.
If these conditions are not present, Active Steer-ing Assist cannot provide assistance.
Active Distance Assist DISTRONIC must beactive in order for the function to be available.
Important safety notes
Active Distance Assist DISTRONIC with ActiveSteering Assist can neither reduce the risk of anaccident if you fail to adapt your driving style noroverride the laws of physics. Active DistanceAssist DISTRONIC with Active Steering Assistcannot take into account road, weather or trafficconditions. Active Distance Assist DISTRONICwith Active Steering Assist is only an aid. You areresponsible for maintaining a safe distance tothe vehicle in front, for vehicle speed, for brak-ing in good time and for staying in lane.
Active Distance Assist DISTRONIC with ActiveSteering Assist does not detect road and trafficconditions and does not detect all road users. Ifyou are following a vehicle which is drivingtowards the edge of the road, your vehicle couldcome into contact with the curb or other roadboundaries. Be particularly aware of other roadusers, e.g. cyclists, that are directly next to yourvehicle.
Obstacles such as traffic pylons at roadworks onthe lane or projecting out into the lane are notdetected.
An inappropriate steering intervention, e.g. afterintentionally driving over a lane marking, can becorrected at any time if you steer slightly in theopposite direction.
Active Distance Assist DISTRONIC with ActiveSteering Assist cannot continuously keep yourvehicle in lane. In some cases, steering inter-vention is not sufficient to bring the vehicle backto the lane. In such cases, you must steer thevehicle yourself to ensure that it does not leavethe lane.
The system may be impaired or may not functionif:
Rthere is poor visibility, e.g. due to insufficientillumination of the road, or due to snow, rain,fog or heavy spray
Rthere is glare, e.g. from oncoming traffic, thesun or reflection from other vehicles (e.g. ifthe road surface is wet)
Rthe windshield is dirty, fogged up, damaged orcovered, for instance by a sticker, in the vicin-ity of the camera
Rthere are no or several unclear lane markingsfor one lane, e.g. roadworks
Rthe lane markings are worn away, dark or cov-ered up, e.g. by dirt or snow
168Driving systems
Driving and parking

Rthe distance to the vehicle in front is too shortand thus the lane markings cannot be detec-ted
Rthe lane markings change quickly, e.g. lanesbranch off, cross one another or merge
Rthe road is narrow and winding
Rthere are highly variable shade conditions onthe roadway
The system is switched to passive and no longerassists you by performing steering interventionsif:
Ryou actively change lane
Ryou switch on the turn signal
Ryou take your hands off the steering wheel ordo not steer for a prolonged period of time
Once you have finished changing lanes, ActiveSteering Assist automatically reactivates.
Active Steering Assist cannot provide assis-tance:
Ron very sharp corners
Rwhen towing a trailer
Rwhen a loss of tire pressure or a defective tirehas been detected and displayed
Observe the important safety notes on ActiveDistance Assist DISTRONIC (Ypage 162).
The steering interventions are carried out with alimited steering moment. The system requiresthe driver to keep his hands on the steeringwheel and to steer himself.
If you do not steer yourself or if you take yourhands off the steering wheel for a prolongedperiod of time, the system will first alert you witha visual warning. A steering wheel symbolappears in the multifunction display. If you havestill not started to steer and have not taken holdof the steering wheel after five seconds at thelatest, a warning tone also sounds to remind youto take control of the vehicle. Active SteeringAssist is then switched to passive. Active Dis-tance Assist DISTRONIC remains active.
